Research
Broadly, I am interested in how we can use linguistics, cognition, and statistics to improve computational models of human language. Currently, I work with Alon Lavie on the AVENUE project, which is leveraging linguistically-motivated syntax to improve machine translation aimed at both resource rich and resource poor languages. My research is focused on developing discriminant syntactic features that help the system choose better translations. This includes both phrase structure and dependency structure and how to best statistically model these structures so that we can capture the behavior of the language pair being translated.
Previously, I worked with Lori Levin and Robert Frederking on a year-long pilot project (also a part of AVENUE) investigating active learning techniques for presenting the a bilingual person with the examples from a linguistically-structured corpus so that such people can be tapped as an efficient and cost-effective resource for improving the quality of machine translation for languages that have few alternatives for acquiring the data needed to traing modern machine translation systems.

The Initial
With apologies to Noah A. Smith, I also feel the need to explain the pretentious middle initial on all my publications: The name Jon Clark is only slighly less common than John Smith. Other Jonathan Clarks include the 2007 CMU MBA class co-president, the songwriter, the photographer, the woodworker, the journalist, the comedian, the cameraman, the actor, the teacher, the pilot, the athlete, the golfer, the biker, the boxing champion, the lighting designer, the British artist, the sculptor, the architect, the health technologist, the computational biology professor, the personal trainer, the wellness professional, the history professor, the chief counsel for Morgan Stanley, the finance professor, the attorney, the founder of Thinstall (virtualization software), the senior VP at Sallie Mae, the real estate agent, the university president, the music professor, the post-hardcore band singer, the founder of Business Writing Solutions, the 18th century general, the basketball player, the NLP trainer (NeuroLinguistic Programming), the telecommunications consultant, the IT professional, the search marketing specialist, the computer engineering student, the polymer research engineer, the physician, another physician, another still, the surgeon, the zoology professor, the biomedial robotics professor (who, incidentally, published a paper with Jorge Cham), and the former CTO of LionBridge (large language engineering company that made this translation software... talk about hard to be unique).
Even the initial doesn't always work; the other Jonathan H Clark is a Texas lawyer.

Personal
When I'm not knee-deep in code, I enjoy going to Pittsburgh Pirates baseball games with my fiancé Libby (while eating nachos topped with obscene amounts of jalapeños), playing drums (jazz, hand percussion, metal, it's all good stuff), and learning bits of random languages.
And of course, reading Jorge Cham's wonderful PhD comics (follow the link for more laughs):
